S2-HD Heavy Duty Bow Spring Centralizer

S2-HD Heavy Duty Bow Spring Centralizer

This heavy duty version of the patented S2 bow spring centralizer is engineered for ultra-high strength in challenging wells.

Single piece construction means the S2-HD has no weak points. It is designed for casing running environments with heavy loads where a solid centralizer may be used traditionally.

The S2-HD is manufactured to gauge. Its exceptional restoring force is delivered with zero start and running forces and generates high levels of stand-off.

S2 centralizer application guide

Performance ratings

Centralization and the ease of running casing is often a balance between strength and flexibility which combine to support, what we call, 'runability'. To help with product selection we've added a rating to all our products for flexibility, runability and inherent strength.
